What it is, in one paragraph

Allergen management is treated as a chemical hazard category under HACCP and is covered by mandatory labelling laws in every major jurisdiction. In Japan, declared allergens follow the national list[2], while exporters and importers must additionally consider EU 1169/2011[3] and the Codex GSFA framework[1].

The 12 terms you must know

  1. Hazard — defined in Codex Annex II and operationalised by national authorities.

  3. PRP (Prerequisite Programme) — defined in Codex Annex II and operationalised by national authorities.
  4. Critical Limit — defined in Codex Annex II and operationalised by national authorities.

Operator dialogue

🦉 & 🐣 & 🐮 — A 5-round operator’s dialogue

🐣
Piyo: Poppo-san, where does allergen actually start in a real kitchen?
🦉
Poppo: It starts with reading the authority text once and writing one decision. Codex sets the international baseline; your national regulator binds you to a specific value or method.
🐣
Piyo: What if the staff resist the new rule?
🦉
Poppo: Show them the failure mode it prevents and the time it saves. Authority handbooks (FSA SFBB, MHLW small-business guidance) describe the minimum viable system — you adapt, you don’t reinvent.
🐮
Mou: Strong, kind, beautiful: allergen made blissful for everyone in the kitchen.

Hibou & Poussin & Vache — dialogue d'exploitant

🐣
Piyo: Les allergènes, est-ce un risque chimique HACCP ?
🦉
Poppo: Oui. Codex CXC 1-1969 catégorise les allergènes comme chimiques; CXC 80-2020 est le code allergénique dédié.
🐣
Piyo: Contact croisé vs contamination croisée ?
🦉
Poppo: Contact croisé = mélange d'allergènes. Pour un coeliaque, même un nuage de farine de blé est dangereux.
🐮
Meuh: Friteuse dédiée sans blé pour 1.000€. Une cliente coeliaque a pleuré de soulagement — investissement remboursé.🐮
🐣
Piyo: Big 9 aux États-Unis ?
🦉
Poppo: FASTER Act 2021 a ajouté le sésame : lait, oeuf, poisson, crustacé, fruit à coque, arachide, blé, soja, sésame.
🐮
Meuh: Loi Natasha 2021 — tous les aliments pré-emballés UK ont désormais étiquetage complet.🐮
